They also warned about loud toys that can harm children's ears. One example they gave was the Dora the Explorer guitar.

Experts said it's not just the toys at Christmas time that can cause the hazard.

"We want to remind parents that there are things we don't think of as a toy, but a child might think of as a toy, like an ornament. They are shiny and bright. Hang chokeable ornaments high enough so kids can't reach them. Remind kids not to chew on wrapping paper. Take it away from them. Foil wrapping paper contains traces of lead. We know its harmful," said Abby Collier of the Children's Health Alliance of Wisconsin.
